YARN-DYEING MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,708, dated November4, 1890. Application iled February 27, 1890. Serial No. 342,027.(Novmodel.)

To all whom it may concern:

Be it known that I, LEONARD WELDoN, of

Amsterdam, in the county of Montgomery, in theState of New York, haveinventednew and useful Improvements in Yarn-Dyeing Machines, of whichthe following, taken in connection with the accompanying drawings, is afull, clear, and exact description. This invention relates to the classof dyeing-machines which are specially designed for dyeing yarn in theskeins; and the invention consists in a novel organization of themachine, hereinafter fully described, and speciically set forth in theclaims.

In the annexed drawings, Figure l' isaside elevation of a yarn-dyeingmachine embodying my invention. Fig. 2 is an end View of the same. Fig.3 is a vertical longitudinal section on line cc, Fig. 2. Fig. 4 is avertical transverse section on line y y, Fig. l. Fig. 5 1s an enlargeddetail-view of the connection of the yarn-supporting bar to its carrieror Fig. 6 is a longitudinal section ofthe same, and Fig. 7 is a detachedperspective View of two links of the barcarrying chain.

Similar letters of reference indicate corresponding parts.

A represents the vat which is to contain the dye-liquor. Said vat ispreferably rectangular or horizontally elongated, and lengthwise overthe top thereof I extend suitable horizontal carriers supported atopposite ends of the vat, and to said carriersI connect bars b b, whichextend across the vat and carry the skeins of yarn suspended in the vat.For said carriers I prefer to employ endless chains C C, passing aroundand carried taut by sprocketwheels D D, which are secured to shafts a a,disposed crosswise of the Vat and journaled in posts P P, attached toopposite sides of the end portions of the vat and rising above the same.The lower portions of said chains between the sprocket-wheels serve ascarriers of the bars bb, which are angular in cross-section and pivotedto the chains, so as to allow said bars to be turned and thereby shiftthe skeins of yarn longitudinally thereon during the dyeing process.

To allow the skeins of yarn to be applied to and removed from the bars bb, when required, I render the bars removable from the chains byemploying metallic journals c, which are separate from the bars b andhave mounted on them collars d, which are adapted to slidelongitudinally on the journals and grip and release the ends of thebars. By means of set-screws e, connected to the collars and engagingthe journals, said collars are retained in posit-ion for holding thebars, as illustrated by full lines in Figs. 5 and 6 of the drawings.

To prevent the skeins of yarn from becoming entangled, I connect to thelower ends of the skeins suitable movable weights, prefer'- ably bars bb', which are inserted and supported in the rows of skeins suspendedfrom the upper bars b b, and in order to maintain the suspended ends ofthe rows ot' skeins uniform distances apart and at the same time subjectthem to greater tension I connect to the ends of the lower bars b bchains C C', which pass with their ends around the sprocket-Wheels D Dand are connected to the upper portions of the endless chains C C. Thechains O O hang slack from the Wheels D D, so as to subject the bars bZJ to the weight of those portions of the chains which are connected tothem.

In order to allow all the upper bars b b to be turned simultaneously ontheir pivots, I fasten to the journalsc star-wheels 1I i and mountcrank-wheels f f on gudgeons secured to the side of the end portions ofthe vat A, and to said crank-wheels I pivot eccentrically the ends of abar B,which is extended lengthwise of the exterior of the vat, as shownin Fig. l of the drawings, and is provided with teeth or projections ZZ, adapted to engage the aforesaid star-wheels d uring the longitudinalmovement of the bar B in one direction.

To the side of one of the crank-wheels f is rigidly attached aratchet-wheel t, with which engages a pawl p, pivoted to a levern,whicl1 is fulcrumedon the vat and receives an 0scillatory motion bymeans of a cam or eccentric o, fixed toa shaft o', which is extendedacross the end of the vat and is mounted in boxes or suitable bearingsattached to the vat and has attached to it a driving pulley or gear I. Aspring s serves to maintain said lever in contact with the aforesaid camor eccentric. The rotation of the latter, together IOO a fisa'roe withthe spring, imparts an oscillatory motion to the lever, and this impartsan intermittent rotary motion to the ratchet-wheel t by means ofthe pawlp. The crank-wheel f, turning with the ratchet-wheel, causes the bar Bto receive a reciprocating motion, in the reverse movement of which thebar is carried in a plane below that in which it is carried in itsforward movement, and during thelatter the teeth Z Zengage thestar-wheels t' fz, and thereby impart to the same and to the bars b b apartial rotation, which causes the skeins of yarn to be shiftedlongitudinally on the bars, and thus carries into the dye-liquor thoseportions of the skeins which have previously been lying on the bars bl).

After the dyeing process is completed the sprocket-wheels D D arerevolved, so that the portions of the chains C C', which carry theyarn-supporting bars b b are drawn toward one end of the vat, and as thesaid bars arrive thereat the attendant of the machine removes them fromthe chains. Another set of bars with yarn hung thereon may then beconnected to the chains and carried to the vat by reversing the rotationof the sprocket-wheels I) D. Motion may be imparted to said wheels byany suitable and well-known means-such as a hand-wheel F, attached toone of the shafts a, as shown.

Ilaving described my invei1tion,wl1atI claim as new, and desire tosecure by Letters Patent, is-

1. In combination with the vat, a series 0f yarn-supporting barsextended across the top of the vat and distributed over the lengththereof and pivoted to their supports, wheels secured to said bars, anda longitudinallymovable bar imparting rotary motion to said wheels, asset forth.

2. In combination with the vat, horizontal carriers extending lengthwiseof the top of the vat and supported at opposite ends of the latter, barsextending across the vat and pivoted to said carriers and carrying theskeins of yarn suspended in the vat, weights movably connected to thelower ends of the skeins of yarn, wheels fixed to the pivoted upperbars, and a reciprocating bar extending lengthwise of the vat andengaging the aforesaid wheels to turn the same, as set forth.

In combination with the vat, horizontal carriers extending lengthwise ofthe top of the vat and supported at opposite ends of the latter,cross-bars pivot-ed to said carriers and carrying the skeins of yarnsuspended in the vat, weights movably connected to the lower ends of theskeins of yarn, wheels fixed to the pivoted upper bars, and a barextending lengthwise of the vat and pivoted eccentrically to rotarysupports and adapted to engage and release the aforesaid wheels7 as setforth.

5. In combination with the vat, two sets of vertical wheels pivoted tosupports on the top ofthe ends of the vat, endless chains extendinglengthwise of the vat and carried on the aforesaid wheels, cross-barsconnected to the lower section of said chains and carrying the skeins ofyarn suspended in the vat, and cross-bars extending through the lowerends of the skeins and supported thereby, substantially as described andshown.

6. In combination with the vat, two sets of vertical wheels pivoted tosupports on the top of the ends of the vat, endless chains extendinglengthwise of the vat and carried taut on the aforesaid wheels,cross-bars connected to said chains and carrying the skeins of yarnsuspended in the vat, cross-bars extending through the lower ends of theskeins, and chains supported at opposite ends on the carrying-wheels ofthe endless chains and having their intermediate portions slack andconnected to the aforesaid lower cross-bars, substantially as describedand shown.
